Whether a roof is installed on a home or a commercial building, its primary purpose is to protect the building’s occupants, structural components, contents and interior furnishings from the elements. However, residential and commercial roofs typically have more differences than similarities. When you need to have a roof installed, replaced or repaired, it is essential to select a local Austin licensed roofing contractor who has experience in the type of roof you have or want.
Commercial & Residential Roofing – Key Differences
Some commercial roofs, particularly on relatively small buildings, have designs that are similar to many homes. For example, gable, dormer, mansard, gambrel, pyramid, hip and combination roofs can be found on both commercial buildings and residences. Therefore, similar roofing materials may be used, including asphalt shingles or metal panels.
What Are the Major Differences Between Residential and Commercial Roofs?
Architects are continually striving to create new designs for residential and commercial properties that are innovative and striking. As a result, either type of structure can borrow features from the other. However, the following items represent the characteristic differences between the two types of properties.
• Size: As a rule, commercial roofs cover a much larger area than residential roofs. For example, the roof covering an average supermarket has an area of more than 42,000 square feet.
• Slope: Most commercial buildings still have flat or low-slope roofs, but the most popular type for homes is a gabled roof with a significant pitch. The slope of a roof is a critical aspect to consider when selecting a roofing material. Asphalt shingles, for instance, cannot be applied to a flat roof, and roll roofing cannot be applied to a pitched roof.
• Complexity: Although a residential roof can be complicated, it typically has few penetrations and little equipment. A residential roofer usually needs to deal with a few vents and perhaps a chimney or skylight. A commercial roofing company must generally contend with rooftop HVAC equipment, pipes and maybe signs.
• Equipment: Commercial roofing requires specialized equipment and tools that are not necessary for residential roofs. Many of the items needed for commercial roofing are not cheap, but they are essential if the roof is to have the proper longevity and retain the manufacturer’s warranty on the materials.
• Skills: Commercial roof services require skills that are not as important for residential work. Membrane roofs are popular for commercial buildings, but the membranes can be damaged if employees do not know how to walk on them, spread them without tearing them or secure them properly. Metal roofing systems are gaining popularity for both residential and commercial applications, but again, these systems require specialized skills.
• Drainage: Proper drainage is critical for both commercial and residential roofing. However, poor drainage on a flat roof can cause problems that are even more severe than poor drainage on a pitched roof. If water accumulates on a flat commercial roof, the roofing materials may be damaged beyond repair, and the building’s structural integrity could be compromised.
